I/O
Outputs the VCXO oscillation waveform.
Inputs the 3.58 NTSC signal, and the output DC becomes 3.2V
O
only for color.
It is 1.4V for Black/white and other signals.
Outputs SCP (Sand Castle Pulse).
O
The output signal is clamp pulse, horizontal blanking pulse, and
vertical blanking.
I/O
I/O pin for controlling the SECAM demodulation IC.
Outputs the Y signal passed through the fsc TRAP (TRAP can be

turned ON/OFF by the bus) and Y delay line circuit.
Outputs the B-Y (U) signal or Q signal.
O
Incorporates the LPF for eliminating carrier.
Outputs the R-Y (V) signal and I signal.
O
Incorporates the LPF for eliminating carrier.
